Meta,
There are several threads on this subject if you do a search for Martin Logan.
It is possible that the panels need to be replaced. This is about the expected life, but my Quests are about the same age and still doing OK. You may be able to solve the problem by unplugging the panels and letting them sit for several hours. Then vacuum them. Humidity or smoke can also cause problems.
Good luck and write me if you can't find what you are looking for in a search.
Happy listening.
